Director Mel Stuart previously directed The Making of the President 1960 (1963) which had been his first feature film, and was about the 1960 U.S. Presidential Election between Richard Nixon and John F. Kennedy.

Jeff Stafford at Turner Classic Movies states that this film is a "a combination of television news footage, archival film, still photographs and recreations of locations and events" and "the majority of Four Days in November (1964) is composed of news feeds, clips from national broadcasts and local Dallas television coverage".

This documentary feature film premiered in New York in the USA on 7th October 1964 which was about a month and a half less than a year after the assassination of U.S. Democrat President John F. Kennedy on 22nd November 1963.

Some movie posters for the film featured such following preambles as (1) "A full motion picture chronicle of the four days our generation will never forget . . . four days that electrified and saddened the world. Included are scenes never before seen on television or the motion picture screen" and (2) "In the memory of man few events have shocked the world as those Four Days in November. Here, with scenes never presented before, is a complete motion picture chronicle of that incredible time in Dallas. Here is the minute-by-minute, hour-by-hour, day-by-day story - with every detail revealed, every question answered".

As the vast majority of the footage utilized for this film was shot for broadcast television purposes, the documentary was released in an aspect ratio of 1.66:1, as close as projection could get to academy ratio while still being formatted for widescreen theatrical presentation.
